Title: Method and system for providing a hardware machine function in a protected virtual machine

Abstract: This invention describes a method and system for virtualizing an internal capability of a computing system; specifically, the invention describes a method and system for establishing a virtual machine containing a programmed hardware-machine function that is normally executed natively as proprietary internal code in its own hardware environment, a Central Electronics Complex (CEC) or logical partition of a CEC. The code resides in a separate hardware domain of the CEC called the Service Element (SE). The IBM VM/ESA (VM) operating system requests the SE to transfer a copy of the code into a virtual machine that VM has initialized, where the machine function is provided (in the current embodiment) as an isolated and encapsulated part of a virtual Parallel Sysplex system comprising multiple virtual CECs in a testing environment.
